QUESTION:

Hello. I have a great 9 acres of black dirt in Dripping Springs! However now that I have cleared cedar, and then w/the great rains came...I am being taken over by wild verbena. (purple)..looks like wild verbena. I have always heard it called that. Any suggestions other than hand pulling?

The best course of action may be no action at all. Last year, a large, newly-cleared area near Driftwood, Texas was awash in Prairie verbena. This year, it has all but disappeared as other, more competitive plant species have taken hold there and are pushing it out.

Prairie verbena serves a vital role in habitat restoration often performed by less desirable, more pernicious non-native plant species of holding newly disturbed soil until more permanent species can take hold and become established. You can think of Prairie verbena as a salve that protects the wounded earth and wears away over time as healing takes place.

If you absolutely have to rid the land of Prairie verbena, hand-pulling is going to be the approach. Other methods simply disturb the soil even more and slow down the process of regeneration that needs to take place.
